Re: chi-square table

Dear Li,

if you're interested in the values rather than
in doing a programming exercise, you can use
the statistics2 package by Shin-ichi Hara:

blade.nagaokaut.ac.jp/~sinara/ruby/math/statistics2/statistics2-0.50/README

From the README:


--- Statistics2.chi2dist(n, x)
Returns the integral of Chi-squared distribution with n degrees of freedom
over (-Infty, x].

--- Statistics2.pchi2dist(n, pr)
Returns the P-value of chi2dist().

--- Statistics2.chi2X_(n, x)
Returns the integral of Chi-squared distribution with n degrees of freedom
over [0, x].

--- Statistics2.chi2_x(n, x)
Returns the integral of Chi-squared distribution with n degrees of freedom
over [x, Infty).

--- Statistics2.pchi2X_(n, pr)
--- Statistics2.pchi2_x(n, pr)
Return the P-value of the corresponding integral.


Best regards,

Axel
